/* =========================================================================
   Agent Governance by Design — landing page.
   Extends styles.css. Reuses the D2B tokens (blue brand, Montserrat/Archivo,
   dark base) — no new colors, no new fonts. Only layout primitives this page
   needs and the homepage doesn't have.

   Body copy inside cards uses --text-2 rather than --text-muted: at 0.45 alpha
   the muted token lands at ~4.4:1 on the dark base, just under WCAG AA.
